100.0 The 100

The Avocado team is proud to present another release: Avocado 100.0, AKA “The 100”, is now available!

Release documentation: Avocado 100.0

Users/Test Writers

  • Asset cache checksum can now use multiple hash algorithms. The ability to store multiple hashes, created by different algorithm to the cache CHECKSUM file was added. This is useful when different tests refer to the same asset, but use different hash algorithms.

  • Information on a test’s file name was introduced in the xunit/junit result files. Although not a standard field everywhere, this information is used and displayed on platforms such as GitLab.

  • Python 3.11 (final) is now formally supported and tested on CI.

  • The runner.output.utf8 and core.input_encoding were settings were removed, and now default to the the system’s setting (by using sys.getdefaultencoding().

  • Command line options prefixed with --nrunner- had that prefixed removed. A command line option such as --nrunner-spawner is now simply --spawner. The matching configuration options such as nrunner.something became run.something. This is due to the fact that nrunner is now the only runner implementation offered by default, so the differentiation and extra typing seems unnecessary. If other runners are added in the future (or by custom, out of tree, plugins) they can choose to respect the existing options if they apply.

  • The avocado jobs get-output-files command was removed. Its original intended purpose has not been relevant for some time, and the preservation of output files are already handled directly by all spawner implementations.

Utility Modules

Bug Fixes

  • Fixed a limit for exec-test and tap tests, where the STDOUT or STDERR buffers could be exhausted, and the test would get stuck forever on further writes. The exec-test and tap runners can now make use of the (optional) output_dir parameter, resulting in a much more efficient I/O handling. When output_dir is used, the only limitation on STDOUT and STDERR is the file-system itself.

  • The --show option was not being respected when running avocado-instrumented tests. The log messages generated by, say, an avocado.test.foo logger, should be presented at the Avocado job UI as it happens, provided --show=avocado.test.foo was given.

  • An existing aid for the usage of Avocado running from Python eggs would result in unnecessary changes to the PYTHONPATH. Those changes could cause unpredictable Python module import behavior.

  • Fixed a condition in which, when failing to import Python modules on tests, the error message returned was Test.__init__() got an unexpected keyword argument 'run.results_dir' which was quite cryptic and confused users.

  • The assets fetch plugin won’t attempt to fetch and cache the assets of the same test more than once.

  • Running tests’ statuses are now properly marked as INTERRUPTED instead of CANCEL when they reach their own (or the job) timeout.

  • The avocado jobs show command used to show a simplified and possibly incorrect information about the spawner used. This information is no longer displayed, given that it’s a test suite attribute, and not really a job level information.

  • The Podman spawner could fail to preserve the output directory when users on the host and the container did not match. This has now been fixed.

Internal Changes

  • The resolver received the same kind of test coverage as the legacy loader architecture, in preparation for the removal of the loader.

  • The Fedora version used on selftests related to the Podman spawner were pinned to 36. The reason is that, because of the release of Fedora 37, which has Python 3.11, no setuptools or Avocado eggs are available for Python 3.11 yet.

  • Removal of the generic avocado-runner runner, which is a reminiscent of the all-in-one nrunner.py file, for ease of deployment. With the nrunner split and now deployed via Python eggs, it does not have to exist anymore.

  • Selftests will no longer not store temporary results in user’s default results directory.
